COMPOSITION FOR COATING MOLDS FOR CONCRETE.

To all whom it may concern:

Be it known that we, WILLIAM W. BEN- NETT and CHARLES S. PILKINc'roN, citizens of the United States, residing at Westerville, in the county of Franklin and State of Ohio, have invented a new and useful Composition for Coating Molds for Concrete, of which the following is a specification.

Our composition consists of'the following ingredients, combined substantially in the proportions stated, viz.,

Gasolene 80% Resin 14% Naphthalene (crystals) 6% Specification of Letters Patent.

Application filed November 4, 1910. seriai'm. 59o,aos.'

Patented Oct. 3, 1911.

By the use of the above composition, the

cement is prevented from adhering to the surfaces of the molds, thus insuring the production of smooth, clean molded surfaces.

As a substitute for the gasolene element of our composition, it will be understood that we may employ grain or wood alcohol, benzin, or naphtha and as a substitute for the resin, paraffin, gum shellac or gumlacquermight be employed, these elements being regarded as equivalents of the gasolene and resin. It is also obvious that any well known or suitable coloring material, may be added to the composition if desired.

We claim:

The herein described composition of matter for coating cement molds, consisting of gasolene 80%, resin 14%, naphthalene (crystals) 6%, substantially as described and for the purpose specified.

In testimony whereof we aflix our signatures-in presence of two witnesses.
